GALEB S. DAVIS, OF HARRISBURG, PENNSYLVANIA.

MACHINE FOR FINISHING COTTON GOODS.

Specification of Letters Patent No. 26,895, dated Januaryl, 1860.

To all 'whom it may concern:

Be it known that I, CALEB S. DAvIs, of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Improvement in Machines for Finishing Cotton Goods; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure A, is a side elevation. Fig. B, is a cross section. Fig. C, is a side elevation. Fig. D, is a top view.

My invention has reference to that class of machines, in which emery rollers and cyllinder brushes are used for cleaning, sprin kling chambers are used for dampening, and calender rollers are used for pressing, smoothing and drying cotton cloths, and the nature of it consists in the peculiar arrangement of emery rollers with partitions in dirt chambers, for cleaning and removing knots and dirt from said cloths; and in the arrangement and use of movable iron stretchers, each with right and left hand threads, for the purpose of laying the nap on the cloth, and preserving its original width, and

also in the application of steam by means of a steam chamber and calender roller, for alternately dampening, bleaching, and pressing, smoothing, and drying the cloth.

For the better understanding of the construction and operation of my machine, I

will describe it by referring to the drawings.

I construct the frame of wood or iron.

(1) is a movable wooden roller which receives the cloth from the loom; (2) is a movable wooden drag roller; (3) is an iron movable drag roller, the cloth runs between these rollers, they connect with each and move by friction; (4) is a stationary iron stretcher with right and left hand threads, which arranges and lays the nap on `the cloth, and preserves its original width, which would otherwise shrink by reason of the strain on it when passing through the machine; (5) is a lower stationary iron stretcher used for the same purpose; (6) is a movable emery roller over which the cloth passes, and removes the knots and dirt from it which fall into the dirt chamber below; (7) is a cylinder brush which rakes the cloth on the under side, removing from it the lint and dirt into said chamber; (8, 9, and 10) are carrying rollers for the cloth; (11) is a movable emery roller which removes the knots and dirt from the cloth into the dirt chamber below; (12) is a cylinder brush which rakes the upper side of the cloth, removing the lint and dirt into said chamber; (13) is a carrying roller for the cloth; (14C) is a steam chamber filled with steam, when the machine is in operation, by means of a pipe connecting it with the boilers, this chamber has an opening in the top over which the cloth runs, and is thus dampened and bleached by the steam; (15 and 16) are movable iron stretchers, running in opposite directions, with right and left hand threads which lay the nap on the cloth and preserves its width while passing between the calender rollers; (17) is an iron movable calender roller running in boxes (M, M); (18) is also an iron movable calender roller resting on roller (17); it is adjustable by means of boxes (32 and 33) in which it runs. These boxes slide up and down in a perpendicular groove in the fra-me, thus enabling this roller to accommodate itself to the thickness of the cloth which passes between said rollers; roller (18) is filled with steam by the same pipe which conducts the steam into the steam chamber. This roller is moved by friction created in resting upon roller (17). It may be driven by gearing so arranged as to connect said rollers. The cloth in passing between these rollers is pressed and smoothed by the pressure of the upper roller upon the lower and dried by means of the steam contained in the said upper roller when the machine is in operation.

(19) is a wooden roller resting on the upper calender roller and running in said perpendicular groove in the frame above mentioned. It slides up and down in this groove Vreceiving the cloth from the ma- -chine and adjusts itself to accommodate the clot-h so received. This roller is moved by friction generated by its contact with the upper calender roller; (20) `is the driving pulley on main shaft; (21) is a loose pulley on main shaft; (22) is a small gear wheel on main shaft between the main driving pulley and side of the machine. This small gear locks into large gear wheel (23); (23) is a large gear wheel on lower calender roller; (24) is a driving pulley on iron movable` stretcher (16), the same being connected by belt with driving pulley (25) on emery roller (6) (26) is a pipe carrying off waterV from steam chamber; (27 is a pipe for supplying steam chamber with steam from the boilers; (28) is a socket valve for regun lating supply of steam into steam chamber; (29) is a pipe for carrying steam into upper calender roller the same connecting with steam pipe (27); (30) isa socket valve regulating supply of steam into upper calender roller; (31) is a steam joint for the admission of steam into upper calender roller; (a, is a double set of levers for v the purpose of applying weight to upper calender roller and so produce a greater pressure on the cloth; (d, d) are connecting rods between said levers; (n, n) are weights applied to these levers; (o, o) are fulcrums for said levers, the first set of which rest on the boXes in which the upper calender roller runs; (34) is a steam joint for egress of steam from upper calender roller; (35) is a socket valve regulating the egress of steam from said roller; (36) is a pipe conducting off steam from this roller; (37 and 88) are two small gear wheels interlocking, and for the purpose of' driving the iron stretcher (15) the same being on the opposite side of the machine from pulley (24) (39) is a large pulley on main shaft opposite the driving pulley, and connecting by belt (z, c', z') with pulleys (41, 42, 43, and 44) and driving the same; (40) is the main shaft of the machine; (41) is a driving pulley on emery roller (11) l(42) is a driving pulleyT on cylinder brush (12); (43) is a driving pulley on cylinder brush (7) (44) is a driving pulley on emery roller (6) The belt (i, z', connecting these pulleys with pulley (39) is arranged as appears inthe drawings; (45) is a dirt chamber inclosing emery roller (11) and cylinder brush (12) having partial partition (y) between them; (46) is also a dirt chamber inclosing yemery roller (6) and cylinder brush (7) with partial partition between them; (47) is a steam pipe running along in and near the bottom of the steam chamber, with holes or openings in its periphery for the escape of steam into the steam chamber. 'I-his pipe is a part of pipe (27) and enters the steam chamber at (51); (48) isa door for removing dirt from chamber (45) (49) is also a door for removing dirt from chamber (46); (50) is the point of connection between steam pipe leading from the boilers and the steam pipe on the machine; (52) is the opening where the water pipe (26) enters the steam chamber; (53) indicates the direction which the main shaft runs Ywhen the machine is in operation; (y, y) are partial partitions in the dirt chambers; (s, s, s) represents the cloth in its passage through the machine. The cloth is fed in from roller (1) and received from the machine by roller (19) are lids or doors which open on hinges, and give an interior view of the machine. The carrying, and emery rollers, also the cylinder brushes rest in'iron boXes which are filled with Babbitt metal. In respect to the use of carrying and emery rollers, cylinderbrushes and calender roller, levers, connecting rods, weights, fulcrums, stationary stretchers, drag rollers, pulleys and gearing and dirt chambers.

My machine is similar to others heretofore used for finishing cotton goods, but the points of difference are as follows: The emery rollers and cylinder brushes have been so arranged in other machines, that those which operated on the upper side of the cloth either discharged the knots, lint and dirt upon the cloth, or upon the rollers and brushes below, thereby causing great inconvenience and virtually counteracting their effect, while those that operated upon the lower side of the cloth discharged the knots, lint and dirt either upon the emery roller below or into the dirt chamber, and in other machines for this purpose Vthe upper calender roller has been heated by hot iron and brick or other similar dense material. But I arrange the emery rollers and cylinder brushes in my machine so that they may operate on both sides of the cloth, as appears in the drawings, discharging. the knots, lint and dirt directly into the dirt chambers. leaving the cloth perfectly clean and free from dirt and foreign substances. I also heat the upper calender roller by the means of steam as above specified. I do not wish to confine myself to this, for either calender roller may be heated by steam and produce the same effect. I also use in my machine iron movable stretcherswith right and left hand threads, also a steam chamber and steam pipes, water pipe, steam joints and socket valves in connection with the same, and also a partial partition in each dirt chamber.

Having thus fully described my invention, I wish it to be understood that I do not claim the emery rollers, cylinder brushes, and calender rollers in themselves; but

What I claim as new and desire to secure by VLetters Patent is- 1. The arrangement of the emery rollers and the cylinder brushes, with the calender rollers, When either calender roller is filled ranged substantially as and for the purpose With steam, substantially as, and for the specified. 10 purposes above specified. In testimony whereof, I have hereunto 2. I claim the iron movable stretchers, the subscribed my name. partial partitions in the dirt chambers, and C. S. DAVIS. the steam chamber into which passes a per- In presence offorated pipe for the purpose of infusing DAVID HARRIS, steam into said chamber, the same being ar- J. S. HILDRUP.
